The Royal Flush system was designed with a 4150 style flange making it an exact fit for the majority of small and big block applications. If your manifold is different, you can simply use a flange adaptor to make it work. The system is generally compatible with stock ignition, but to take advantage of timing control features that the system offers, you'll want to use a magnetic pickup distributor and separate ignition coil- both of which are included in our Top End and Master Kits!
Computing Power
A robust remote-mounted ECU that utilizes our OEM standard 32-bit architecture. This allows the system to manage input/output signals, voltage, and RPM faster and more consistently than our competitors. A remote-mounted ECU allows it to avoid dreaded heat-and-vibration induced hardware failures that are prevelant in other aftermarket systems.
Plug 'n' Play
Not a tuning wiz? You don't need to be since we provide a wizard for you. Our self-learning* functionality means you only have to answer a few basic questions in the startup wizard and then the ECU takes care of the rest. After about 30-60 mins of idling and drive time, the system will build it's own tune so you don't have to. Click here to learn more about our handhelds and dashes and see all of their features.
*Self-learn works best for stock-mild applications. For more aggressive applications and even some stock-mild applications, we offer free tuning software on our website.
Boost it, baby!
Each TBI unit comes with a built in 3 bar MAP sensor that will allow you to run up to 27lbs of boost!

Aces EFI’s Royal Flush™ EFI/CDI is the most powerful TBI system on the market! Integrating our EFI control module and CDI ignition system inside one ECU, this is a revolutionary upgrade and huge leap forward in the world of aftermarket EFI products. By using CDI, you are able to create a much hotter spark in order to burn fuel more efficiently and ensure maximum power, especially in boosted and performance applications.
The Royal Flush EFI/CDI system utilizes four 100 lb./hr. fuel injectors, giving the system the capability of supporting up to 650 horsepower. The system includes the throttle body (with integrated fuel injectors, TPS sensor, MAP sensor, IAT sensor, and stepper motors), wiring harness, wideband O2 sensor, ECU, and a 5” touchscreen handheld programmer for easy tuning and monitoring of engine data.
The system fits any 4150-flange 4-barrel intake manifold and is designed for easy installation and tuning. Installation is straightforward and easy, and the system includes everything you need to get on the road or track quickly. For stock to mild applications, the calibration wizard and self-learning features mean advanced tuning knowledge or experience is not required. But for more aggressive or performance oriented applications, Aces offers a full tuning software suite and USB data cable for advanced manual tuning.
Aces designed its throttle body systems with the ECU separate from the throttle body. This alleviates any issues with possible damage to the ECU from unwanted engine heat or vibration. This is a common problem with other “all-in-one” style systems on the market.
Whether you are building a budget beater or a boosted racing car, Aces EFI’s Killshot™ EFI kit has the technology and advanced features you need, in an easy-to-install, easy-to-tune package so you can take your ride to the next level!

Marine Applications?
Is it marine or coast guard approved/certified? No. None of our products are.
Do we recommend it? No, since water and engines don't generally mix and warrantying items in these conditions becomes tricky. These are also modified applications that are not 100% what the systems were designed for.
Will it work? Yes, with some modifications for the WBO2 sensor.
Is it E85 compatible?
Yes, you just would need to change some settings first in order for it to work.
Please note that damages to the system caused by the use of E85 or other racing fuels are not covered by our warranty policy. This is because E85 is known to corrode certain types of material over time and our systems were not designed for long-term E85 use.
Will it work with aftermarket or stock gauges?
The system is not generally setup to work with stock gauges which is why we provide the handheld to display all the readings. Aftermarket tachometers will work with the system, and we are working to provide support for other popular aftermarket gauges soon!
What is your warranty policy?
All products have a limited one year warranty against any defects or quality of workmanship from date of purchase.
Our warranty is extended to the original consumer only. This limited warranty is not assignable or otherwise transferable. Customers must provide proof of purchase for warranty claims.
Aces’ warranty does not apply to products, which have been:
- Modified or altered from factory condition.
- Subjected to adverse conditions, such as misuse, neglect, accident, improper installation or adjustment, dirt or other contaminants, water, or corrosion.
- Installed in other applications not recommended by Aces Fuel Injection.
What is your refund and return policy?
Aces Fuel Injection is happy to accept returns on orders returned to us inside our policy as long as they are new and unused. In general, items must be returned within 30 days for a full refund or within 60 days for a 10% restocking fee.
For our full Refund & Return Policy, that has all of the fine print, you can access it here.
What kind of tech support do you offer?
Aces offers general support on product setup, installation, troubleshooting, and basic diagnostic help.
While most stock-mild applications do not require tuning, some applications (usually more aggressive cams or boosted applications) may require additonal tuning beyond what the self-learn is capable of. Aces does not offer custom tuning though we can recommend Authorized Aces Tuners who may charge a fee for their services. Read more about our support services and what to expect here.
